Application filed January 27, 1927. Serial No. 1 3,927.

This invention relates to means for con densing anti-freezing, solutions, such; as alcohol, which are used ,in cold weather in radiators of automobiles and other motor vehicles, and the primary object is to provide a neat, efficient and comparatively simple device for attachment to the neck of the radiator, which will receive the steam and vapors, condense them back into liquid form, and return the liquid to the radiator. Further and more specific objects w1ll be disclosed in the course of the following specification, reference being had to the accompanying drawing, in which:

Fig. 1 is a sectional elevation through the neck and adjacent parts of a radiator, and through a major portion of the condenser.

Fig. 2 is a sectional elevation about as on the line 22 in Fig. 1.

Referring to the drawing more particularly and by reference characters A designates a radiator, having a neck B, an overflow pipe C, and a baffle plate I), which is frequently found in radiators where the water is circulated by a pump and is used to prevent splashing of the water E up into the neck B. I provide the neck B with a cap F which carries my improved condenser.

The condenser consists, primarily, of a casing 3, of a general circular form, and having ashank t which is secured in the cap F by a nut 5. The casing is provided with two semi-circular chambers 6 and 7, separated by partitions 8 and 9, and which respectively communicate with passages 10 and 11 which extend through the shank 4. Both chambers 6 and 7 communicate with a release valve 12 consisting of a nipple having a ball 13 held down by a spring 14, and the tension or pressure of this spring may be regulated by a set screw 15, secured by a lock nut 16. The valve is further provided with a vent 17 through which the steam may escape when the pressure is great enough to unseat the valve ball 13. In order that none of the steam or vapors may escape through the usual overflow pipe C, and thus result in loss of the anti-freezing solution, I provide this pipe with a suitable stopper, such as 18, with a result that the valve 12 must be pro vided in order to relieve the internal pressure if and when the condensation process does not equalize the process of vaporization. The steam and vapors are discharged up into the passage 10, as it is open to the space above the liquid level. The return passage 11, however, is provided witha pipe 19 which extends back into the liquid body E. It will be noted that this pipe 19 is offset, as at 20, the object being to make itslowcr portion concentric with the cap F. Thus, only acomparatively small holeneed be madein the plate D to receive the pipe. .The chambers 6 and 7 are connected by a series of transversely arranged tubes 21, which act as condensers, and these tubes are inclined so as to deliver the condensed liquid into the chamber 7, from which it drops down, through 11 and 19, in its return to the radiator. The tubes are spaced from each other so as to present as large a cooling surface as possible, and this surface is supplemented .by the surfaces of vertically arranged finsor plates 22, through which the tubes extend and by which they are firmly held in position. U

It is understood that suitable modifications may be made in the general design and nunicates with the space above the liquid.

level of the radiator, and the other of which is arranged to communicate with the liquid below said level, and a series of condenser tubes connecting said chambers.

2. A condenser, for motor vehicle radia-" tors, comprising a casing having two laterally arranged chambers, one of which communicates with the space above the liquid level of the radiator, and the other of which is arranged to communicate with the liquid below said level, and a series of condenser tubes connecting said chambers, said tubes being inclined whereby condensate will flow into said other chamber.

3. A condenser for motor vehicle radiators, comprising a casing having two laterchambers, and a series of plat-es contacting With said tubes for bracing the same and supplementing the cooling area thereof.

4. A condenser of the characterdescribed comprising a ring shaped shell having partitions dividing it into two semi-circular chambers, a pressure releasable valve communicating with the shell, and a series of condenser tubes extending transversely across the shell to connect the said chambers.

5. A condenser of the character described comprising a ring shaped shell having partitions dividing it into two semi-circular chambers, a pressure releasable valve communicating with the shell, and a series of condenser tubes extending transversely across the shell to connect the said chambers, said condenser tubes being inclined.

6. A condenser of the character described comprising a ring shaped shell having partitions dividing it into two semi-circular chambers, a pressure releasable valve communicating with the shell, and a series of condenser tubes extending transversely across the shell to connect the said chamhere, said valve being adjustable whereby the predetermined internal pressure in the condenser may be limited as desired.

In testimony whereof I affix my signature.
